Floating or Sinking?
Increase or Decrease?
Which has greater pressure?
Which Principle?
100
The force exerted on a surface divided by the total area over which the force is exerted.
What is pressure?
100
The force that pulls objects toward each other.
What is gravity?
100
Pressure does this as the area over which a force is distributed increases.
What is decreases?
100
A skydiver or a boat on the ocean?
What is Boat?
100
This principle states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces.
What is Archimedes' Principle?
200
The ratio of the mass of a substance to its volume.
What is density?
200
A measure of the force of gravity on an object.
What is weight?
200
As your elevation increases, atmospheric pressure does this.
What is decreases?
200
A skydiver at 3,000 m or a mountain climber at 8,000 m?
What is the skydiver?
200
When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
What is Pascal's Principle?
300
An upward force.
What is lift?
300
The upward force exerted by a fluid on a submerged object.
What is buoyant force?
300
Water pressure increases as depth does this.
What is increases?
300
The pilot at a commercial airplane or a scuba diver?
What is the scuba diver?
300
This principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases.
What is Bernoulli's Principle?
400
A substance that can easily flow.
What is fluid?
400
Changes in this cause a submarine to dive or rise.
What is density?
400
Bernoulli's principle states that as the speed of a moving fluid increases, the pressure within the fluid does this?
What is decreases?
400
An aircraft carrier or a submerged submarine.
What is the submarine?
400
The principle that explains what an auto mechanic uses and works with every day.
What is Pascal's Principle?
500
An instrument used to measure atmospheric pressure.
What is a barometer?
500
The buoyant force acts in the direction opposite to the force of gravity, so it makes an object feel this.
What is lighter?
500
In a hydraulic device, a force applied to one piston does this to the fluid pressure equally throughout the fluid.
What is increases?
500
A scuba diver at 15 m deep or a scuba diver at 50 m deep?
What is the scuba diver at 50 m deep?
500
The principle that is used every day by airplanes and helicopters.
What is Bernoulli's Principle?
